Product Description:

The MHD112D-027-PG0-LN servo motor is produced by Bosch Rexroth Indramat within the MHD Synchronous Motors series. This permanent-magnet unit supplies controlled rotary motion for industrial automation axes such as gantry drives, press feeders, and packaging turrets, where commanded position and velocity must follow the drive controller precisely. The motor functions without a holding brake, so static load retention must come from the drive.

At stall, the motor develops 48.0 Nm of continuous torque, and that output is sustained because the stator jacket is equipped for liquid cooling that removes resistive heat quickly. A sealed housing rated at IP65 blocks dust and low-pressure water so the motor can be mounted close to the work zone. The square flange measures 192 mm, and a 130 mm centering diameter aligns the motor concentrically to gearboxes or machine frames. A plain shaft transfers torque, and a shaft seal protects the internal bearings. Electrical power reaches the stator through a left-facing power connector, and digital servo feedback with an integrated optical encoder returns speed and position data from the same side. The windings follow code 027, the insulation is Class F, and the D-length frame in size 112 keeps the overall length short. Rated operation is permitted from 0 °C to 40 °C ambient and up to 1000 m above mean sea level.

For precision tasks, the feedback system provides ± 0.5 angular minutes of system accuracy with absolute position detection over more than 4096 revolutions, allowing homing-free startup after power loss. The optical measurement method eliminates mechanical wear, while the encoder electronics remain protected behind the shaft seal. Storage and transport are allowed between -20 to +80 °C, which supports handling and warehousing when the motor is kept as a spare.
